Fire Sentry SS2 Flame Detection

SS2 Flame Detector

The Fire Sentry SS2-AM and Fire Sentry SS2-AML are the ultra-high-speed digital Multi-Spectrum optical models of the Fire Sentry SS2 UV/IR Flame Detectors. These detectors feature ultra-high-speed responses to explosive fires and are typically used in munitions production, explosives production, and special applications.

The field of view for the Fire Sentry SS2 Flame Detector is the widest in the industry with a 120° cone of vision. This means each detector can cover a more hazardous area. Greater sensitivity also increases the volume covered by each detector, up to four times more than some other detectors.

Using sophisticated microprocessor signal processing algorithms with complete spectrum information, virtual immunity to false alarms from arc welding, corona discharge, and other common UV sources is achieved.
